* The Tyrannosaurus might have had lips, a new study suggests * Researchers compared skulls and studied teeth for the study * Some scientists aren't convinced about this theory FILE – Stan, one of the largest and most complete Tyrannosaurus rex fossil discovered, is on display, Tuesday, Sept. 15, 2020, at Christie’s in New York. The teeth on T. rex and other big theropods were likely covered by scaly lips, concludes a study published Thursday, March 30, 2023, in the journal Science. The dinosaur’s teeth didn’t stick out when its mouth was closed, and even in a wide open bite,...

The fossilized skeleton of a T. rex relative that roamed the earth about 76 million years ago will be auctioned in New York this month, Sotheby’s announced Tuesday. The Gorgosaurus skeleton will highlight Sotheby’s natural history auction on July 28, the auction house said. The Gorgosaurus was an apex carnivore that lived in what is now the western United States and Canada during the late Cretaceous Period. It predated its relative the Tyrannosaurus rex by 10 million years. The specimen being sold was discovered in 2018 in the Judith River Formation near Havre, Montana, Sotheby’s said. It measures nearly 10...

A total of 2.5 billion Tyrannosaurus rex probably existed during the lifespan of the species, researchers have calculated – suggesting that very few survived as fossils. Charles Marshall at the University of California, Berkeley, and his colleagues used body mass and population density to estimate how many T. rex once lived. Larger animals tend to have a larger individual range, because they need more food to support their body mass than smaller animals, meaning body mass is inversely correlated with population density – a rule known as Damuth’s law. Previous analysis of T. rex fossils shows that the average body...

Although past research has suggested Tyrannosaurus rex was related to chickens, now findings hint this giant predator might have acted chicken too. Instead of picking on dinosaurs its own size, researchers now suggest T. rex was a baby killer that liked to swallow defenseless prey whole. Fossil evidence of attacks of tyrannosaurs or similar gargantuan "theropods" on triceratops and duck-billed dinosaurs has been uncovered before, conjuring images of titanic clashes.

A man flouted Spain's coronavirus quarantine rules by taking out the rubbish while dressed as a dinosaur. Police officers stopped the man - who was wearing a tyrannosaurus rex costume - and gave him a warning as he waddled away from a street-side bin where he had just dumped a bag. The bizarre incident in Vistabella, Murcia, happened days into a government-imposed lockdown to stop the spread of coronavirus. Residents and tourists alike are banned from going outside except to buy food, go to work or get medical help for 15 days.

The Tyrannosaurus rex may be among the most well-known and terrifying dinosaurs to walk the Earth, but a newly discovered 4-foot cousin was likely just as scary. Known as Moros Intrepidus (which means "harbinger of doom"), this tiny tyrannosaur lived 100 million years ago. Despite its diminutive size, it was still lethal, North Carolina State University paleontoloist Lindsay Zanno said. “Moros was lightweight and exceptionally fast,” Zanno said in a statement. “These adaptations, together with advanced sensory capabilities, are the mark of a formidable predator. It could easily have run down prey, while avoiding confrontation with the top predators of...

With a roar loud enough to shake a forest and a green, scaly skin, it has long been regarded as the slickest villain of the prehistoric world. But according to a new TV programme, Tyrannosaurus Rex looked entirely different to the terrifying image so familiar from depictions on the silver screen. According to a new documentary, Tyrannosaurus Rex may not have been as terrifying as its depictions on the silver screen According to a new documentary, Tyrannosaurus Rex may not have been as terrifying as its depictions on the silver screen The dinosaur had black, bristly tufts of feathers and...

The fearsome roar of Tyrannosaurus Rex as portrayed in film has left many a cinema-goer quaking in their seat. But new research suggests the king of the dinosaurs made a far more sinister sound. For a new BBC documentary, naturalist Chris Packham visited Julia Clarke, professor of Vertebrate Palaeontology at the University of Texas, to test out a the theory that dinosaurs actually sounded more like birds and reptiles, than today’s predatory mammals. “The most chilling noises in the natural world today come from predators, the howl of the wolf, the roar of the tiger, but experts now doubt that...

Monopoly is making changes: The boot has been booted, the wheelbarrow has been wheeled out, and the thimble got the thumbs down in the latest version of the board game. In their place this fall will be a Tyrannosaurus rex, a penguin and a rubber ducky. …

The collective noun is a terror of tyrannosaurs: a pack of the prehistoric predators, moving and hunting in numbers, for prey that faced the fight of its life. That tyrannosaurs might have hunted in groups has long been debated by dinosaur experts, but with so little to go on, the prospect has remained firmly in the realm of speculation. But researchers in Canada now claim to have the strongest evidence yet that the ancient beasts did move around in packs. At a remote site in north-east British Columbia - in the west of Canada - they uncovered the first known...

The controversial discovery of 68 million-year-old soft tissue from the bones of a Tyrannosaurus rex finally has a physical explanation. According to newly published research, iron in the dinosaur's body preserved the tissue before it could decay. The research, headed by Mary Schweitzer, a molecular paleontologist at North Carolina State University, explains how proteins — and possibly even DNA — can survive for millennia. Schweitzer and her colleagues first raised this question in 2005, when they found the seemingly impossible: soft tissue preserved inside the leg of an adolescent T. rex unearthed in Montana.

A fossil tooth found buried inside the healed tailbones of a duckbill dinosaur suggests the animal survived a close encounter with a Tyrannosaurus rex about 65 million years ago, according to a new study. Scientists say the embedded tooth, discovered in the Hell Creek Formation in Montana, is the first conclusive proof that T. rex was not just a scavenger, but also a predator that hunted and killed prey... But not everyone agrees. Jack Horner, a paleontologist at Montana State University who has long argued that T. rex was incapable of hunting healthy adult prey, remains unconvinced... The fossil evidence...

Tyrannosaurus rex was far from a plodding Cretaceous era scavenger whose long tail only served to counterbalance the up-front weight of its freakishly big headTyrannosaurus rex was far from a plodding Cretaceous era scavenger whose long tail only served to counterbalance the up-front weight of its freakishly big head. T. rex's athleticism (and its rear end) has been given a makeover by University of Alberta graduate student Scott Persons. His extensive research shows that powerful tail muscles made the giant carnivore one of the fastest moving hunters of its time. As Persons says, "contrary to earlier theories, T. rex had...

A dinosaur bone buried for 80 million years has yielded a mix of proteins and microstructures resembling cells. The finding is important because it should resolve doubts about a previous report that also claimed to have extracted dino tissue from fossils...

THE biggest, and possibly the baddest predatory dinosaur of them all was not the fabled Tyrannosaurus rex, or even its slightly larger rival Gigantosaurus, but a long-jawed, sail-backed creature called Spinosaurus. An examination of some newly obtained fossils shows that Spinosaurus stretched an impressive 17 metres from nose to tail, dwarfing its meat-eating relatives. As well as being longer than its rivals, Spinosaurus also had stronger arms with which to catch its prey, unlike the puny-armed T. rex and its ilk. Until 10 years ago, T. rex held the mantle of the biggest predatory dinosaur. Of the 30 specimens collected...

Alive as dinosaurs may seem to children, knowledge of them as living creatures is limited almost entirely to what can be learned from bones that have long since turned to stony fossils. Their soft tissues, when rarely recovered, have lost their original revealing form. A 70-million-year-old Tyrannosaurus rex recently discovered in Montana, scientists reported today, has apparently yielded the improbable: soft tissues, including blood vessels and possibly cells, that "retain some of their original flexibility, elasticity and resilience." In a paper being published on Friday in the journal Science, the discovery team said that the remarkable preservation of the tissue...

The earliest known relative of the mighty Tyrannosaurus rex had primitive feathers, probably to help it keep warm. Researchers at the Chinese Academy of Sciences in Beijing found the remains of the early tyrannosauroid which roamed the earth between 139 and 128 million years ago, in western Liaoning, China, an area rich in fossil remains. "This provides the first direct fossil evidence that tyrannosauroids had protofeathers," Xing Xu, one of the scientists, said in a report in the science journal Nature. The primitive feathers were found on the remains of a dinosaur called Dilong paradoxus, which was about 1.5 yards...

New Dino Resembles T. Rex, B. Bunny AFP The Buck-Toothed Beauty Sep. 18 — The world's greatest team of fossil hunters are scratching their heads over their latest find — a unique dinosaur whose distant cousins were mighty carnivores, yet which has two bucky front teeth, rather like a rabbit's. The creature has many of the features of the oviraptor, a small two-legged dinosaur that, as a theropod, was distantly related to the Tyrannosaurus rex. Instead of having the carnivore's typically long, sharp teeth, oviraptors had a rounded, parrot-like beak which they used to steal eggs from nests. But the...
